RESILIENT TIRE.

SPECIFICATONforming part of Letters Patent No. r771,272, dated October 4, 1904.

Application filed October 30, 1903.

To a/Z/l whom, it nca/,y concern:

Beit known that we, SAM THOMAS RICHARD- soN and RICHARD PRICE, coach-wheel manufacturers, subjects of His Majesty the King of Great Britain and Ireland and of the British Dominions Beyond the Seas, Emperor of India, both residing at 3a Rea street, in the city of Birmingham, England. have invented certain new and useful Improvements in or Relating to Pneumatic Tires and other Resilient Tires, of which the following is a specification.

This invention has reference more particularly to pneumatic tires of the kind which are known as single-tube tires and in which a large portion of the tire is inclosed in the trough-section wheel-rim, the tire being made with a thickened tread which extends through the contracted periphery of the rim; but this invention can also be applied to solid indiarubber and other resilient tires, the object of this invention being to provide simple and eiicient means to prevent the tire from creeping along the wheel-rim.

We will describe this invention by referring to the accompanying drawings, on whichw Figure 1 is a cross-section of a single-tube pneumatic tire constructed in accordance with this invention, suitable more particularly for a motor-car or a road-vehicle, this view showing also a cross-section of the wheel-rim and a portion of one of the spokes and the screw which secures the spoke to the wheel-rim. Fig. Qlis a sectional side elevation of the same. Fig. 3 is a sectional side elevation, and Fig. 4. is an inverted plan, of a portion of the pneumatic tire shown in Figs. 1 and 2,'but drawn to a smaller scale than are those figures. Fig. 5 is a crosssectional view showing the same tire and wheel-rim as in the preceding figures, but arranged for wire spokes and nipples. Fig. 6 is a side elevation of the spoke-nipple shown in Fig. 5. Fig. 7 is a side sectional elevation of the same pneumatic tire shown in the preceding figures, but with the wheelrim differently constructed and forming a modification of our invention.

The same letters of reference indicate the same or corresponding parts in all the figures. A is the trough-section wheel-rim, and B is Serial No. 179,215. (No model.)

the single-tube pneumatic tire, the solid indiarubber tread part b/ of which protrudes through the trough of the rim.

In carrying out this invention we provide in the bottom of the trough-section wheel-rim A a series of projecting studs, such as O, preferably of a dome shape and arranged at regular intervals apart all round the wheel-rim, and in the pneumatic tire B we provide a series of corresponding depressions, such as b2, made of the same shape as the studs C and at the same distances apart, so that when the tire B is placed in position in the trough-section wheel-rim, as in Figs. 1 and 2, and inflated these studs or projections C will take into the holes or depressions b2 in the tire B and elfectually prevent the same from creeping. As will be seen by the drawings, the depressions 52 are molded in the tire, so that there are corresponding domed projections b3 in the interior of the tire, and the thickness of the tire is not in any way diminished at the depressions b2. rim A may be formed in various ways-as, for instance, they may, as shown in Figs. l and 2, be the heads of the screws which secure the spokes to the wheel-rim. A portion of one of the spokes is here shown and marked D, or, as shown in Fig. 5, the said projections, one of which is here shown and marked O', is the head or end of the'nipple E, which secures the spokes to the wheel-rim. In this figure one of the nipples E is shown and also one of the wire spokes F, and this nipple E has a domed head O at the bottom of the in. terior of the trough A, corresponding with and to take into the corresponding depressions b2 in the pneumatic tire, or, as shown in Fig. 7 the said studs, which in this case are marked G, areentirely separate from the spokes D and are riveted to the wheel-rim A at the proper distances apart to correspond with the depression b2 in the tire. Our invention is similarly applied to solid india-rubber and like resilient tires which we make with depressions similar to Z22 round their inner periphery to take onto corresponding projections-such as O or C or G or I-in the wheelrim to prevent creeping, as above described.

The projecting studs C in the What We claim as our invention, and desire to secure by Letters Patent, is-

1. A pneumatic tire or other resilient tire made with depressions such :Ls b2 on its inner periphery at regular intervals apart and adapted to engage with corresponding studs or projections et the bottom of the trough-section Wheel-rim so as to prevent the tire from creeping, said depressions forming dome-shape projections in the interior of the tire, substantially as set forth.

2. The improved single-tube pneumatic tire consisting of the air-inliated portion B to be
